The 3D and latest 4D appear to be the more balanced tyre for our typical UK winters. From what I read the M3 has a slightly more severe winter bias, but still a HP winter tyre and for the top end of the market.

Well put the Winters on the 5er this morning.

After a day out, coming home it's now 4c and I pull onto a damp road and give the accelerator a good push...no wheel spin or DSC light. Pretty sure the summers in these conditions would have twitched.
